I-Ferrule

Ngakho-ke yini i-ferrule?Ngokuvamile, noma yiluphi uhlobo lwebhande noma isiqeshana esisetshenziselwa ukuxhuma, ukuqinisa noma ukuvikela izinto ndawonye.Incazelo ebanzi ehlanganisa yonke into kusukela kumabhande afakwe ekugcineni kwezintambo zezicathulo ukuze zingaqaqeki, kuya eziqeshaneni zensimbi eziqinile. esetshenziswa ukuxhuma izintambo zocingo ndawonye.Kodwa emhlabeni wezintambo, ama-ferrules anencazelo ecacile futhi anenhloso ehluke kakhulu kunezinsimbi ezisetshenziselwa ukusetshenziswa kwemishini kuphela.
I-wire ferrule iyishubhu lensimbi elithambile elibosheka kuze kube sekugcineni kwentambo eboshiwe ukuze kuthuthukiswe izici zokuxhuma zocingo.Izinsimbi eziningi zenziwe ngethusi, ngokuvamile zenziwe ithini.Izinsimbi zilinganiswe ngosayizi wegeji ethile yocingo, womabili ububanzi. nobude.Nokho, i-ferrule ingaphezu kwe-cylinder elula - inodebe noma i-flare engxenyeni eyodwa eqoqa futhi ihlanganise umucu owodwa wocingo lapho i-ferrule ifakiwe.
Ukuqubuka kwezinsimbi eziningi akubonakali ngokushesha ngoba ngokuvamile kuvame ukugoqwa ngomkhono wokufaka wekhebula lepulasitiki elicijile. i-ferrule.Ngokungafani nokunye okuvamile okuxhumeke ku-crimp, umkhono wepulasitiki we-ferrule awucindezelwa ngesikhathi sokufakwa.Uhlala uqinile eduze nendawo yokufaka futhi uhlinzeka ngezinga elithile lokukhululeka ngemva kokufakwa ngokususa irediyasi yokugoba yocingo isuke ekugcineni kwendawo yokuhlanganisa. .Imikhono eminingi ye-ferrule inekhodi yombala ngosayizi wezintambo ezingeni le-DIN 46228, okudidayo, elinamakhodi amabili ahlukene, isiFulentshi nesiJalimane, ngamamilimitha ayisikwele endaweni efanayo ye-cross-sectional.
Uma i-ferrule izwakala njengento yaseYurophu kunento yaseMelika, lokho kungesizathu esihle. Ukuze uthole isitifiketi se-CE, izinto zikagesi kufanele zinqamule izintambo eziboshiwe zibe isikulufu noma amatheminali entwasahlobo ngama-ferrules.Awukho umthethonqubo onjalo e-US, ngakho-ke ukusetshenziswa kwama-ferrules emishinini yase-US akuvamile.Kodwa ama-ferrules anezinzuzo ezithile okunzima ukuziphika, futhi ukutholwa kwazo kubonakala kusabalala ngoba kwenza umqondo omuhle wobunjiniyela.
Ukuze uqonde ukuthi kanjani, qinisa ucezu olufushane lwentambo evalekile yanoma iyiphi igeji.Intambo eboshiwe iyagobeka, okungesinye sezizathu zokuthi kungani kusetshenziswe ucingo olucijile esikhundleni socingo oluqinile ezinhlelweni eziphathwayo kanye namandla okudlidliza.Kodwa isaqinile kancane. , ngokwengxenye ngenxa yokuthi i-insulation igoqa izintambo ze-conductor, igcine isondelene futhi igcina imicu ngayinye isongwe noma ibekwe ngaphandle. Izintambo okungenani ziphazamiseke kancane - ziqaqa kancane. Hlubula okuningi kokuvala futhi imicu iya ngokuya ihlukana. Susa konke ukugquma futhi amakhondatha azolahlekelwa yikho konke ubuqotho besakhiwo futhi awele emicu ngayinye.
Lena inkinga eyisisekelo exazululwa ama-ferrules: Ngemva kokukhumula, agcina isibopho esiqinile phakathi kwezintambo ku-conductor futhi avumele uxhumano ukuba luqhube umthamo walo olinganiselwe. kwemicu eyodwa eyenza ukuthintana okuqinile netheminali.Lokhu kunqanyulwa kunokumelana okuphezulu kakhulu kunokuxhumana kwe-ferrule efanele.Ukusebenza kwentambo eboshiwe enezinsimbi kungcono kakhulu kunokungenazo izinsimbi.Umthombo: Weidmüller Interface GmbH & Co. KG
Ukuxhunywa kwe-ferrule kwenza okungaphezu nje kokunciphisa ukumelana, noma kunjalo.Njengezinye izixhumo ze-crimp, izintambo zocingo ngaphakathi kwe-ferrule efakwe kahle zingaphansi kwengcindezi enkulu, zinwebeka nge-axially futhi ziwohloke ngokwe-radial lapho inqubo iqhubeka. izintambo, kuyilapho ukucindezelwa kwe-radial kuvame ukususa izikhala zomoya phakathi kwezintambo.Lokhu kuvame ukwenza ukuxhumana okucijile kube ngcono ekumelaneni ne-oxidation kunezintambo ezingacushiwe, okwandisa impilo yokuxhuma.
Ngakho-ke ingabe ama-hoops ayindlela yokuya kubadlali bomndeni? Sekukonke, ngingathi yebo. Ama-Ferrules anezinzuzo ezicacile ngaphezu kwentambo evamile enentambo, futhi ezinhlelweni zamanje eziphakeme nginganamathela ekuyisebenziseni ngamatheminali ayisikulufu, noma yikuphi lapho ingcindezi ikhona khona. ukhululekile.Futhi, anikeza amaphrojekthi ukubukeka okuhlanzekile, okuchwepheshile, ngakho-ke ngivame ukuwafaka ekuxhumekeni kwezintambo zami ezicishiwe ngisho noma uhlelo lokusebenza lungabalulekile.Kunjalo, ukusebenzisa ama-ferrules akulula, kodwa kungu-$30 ngekhithi. ngama-ferrules ahlukahlukene kanye namathuluzi afanele wokuhlikihla, akukubi lokho.
"Intambo eboshiwe iyagobeka, okungesinye sezizathu zokusebenzisa intambo ebambekile esikhundleni socingo oluqinile ezinhlelweni ezisetshenziswayo kanye namandla okudlidliza."
Awunaso isixhumanisi senkulumo oyithumele emasontweni ambalwa edlule mayelana nokuxhuma izitho zamapayipi nokusebenzisa ama-ferrules?Leyo vidiyo ingenze ngawathanda ama-ferrules futhi manje sengiyawathanda.
I-Phoenix Contact yenza ithuluzi elihle elihlanganisa amamagazini (njengezibhamu) alayishwe ngaphambili ngama-ferrules anosayizi abahlukahlukene ashelela ethuluzini.

Uma ufuna ukungena emininingwaneni ngempela, kunencwadi enhle kakhulu ka-Wurth elektronik http://www.we-online.com/web/en/electronic_components/produkte_pb/fachbuecher/Trilogie_der_Steckverbinder.php
Ibhonasi: Uma ukwazi kahle konke lokhu okungenhla, ungasebenza ngaphandle kwezinkinga kunoma iyiphi imboni enkulu, futhi kunobuhle obuthile bokuxhuma izixhumi ngendlela efanele.
I-Knipex ref 97 72 180 Pliers.Kukhokhelwe cishe ama-euro angu-25 ukuze kunqanyulwe ikhebula lezintambo ezingaba ngu-300 liphela ngawo, futhi ngizowasebenzisa kakhulu ngesonto elizayo ukuze ngifake kabusha ama-electronics kumzila we-CNC. Nokho, esikhundleni sokuthenga i-ferrule eshibhe kakhulu, thenga i-ferrule enegama (njenge-Schneider).
Uhlaka lwe-Pressmaster MCT kanye ne-plug-in thingie elungile (die).Uhlaka lungaba ngu-$70, isikhunta silinganiselwa ku-$50, nika noma thatha.Lena into engcono kakhulu engiyithole ngemva kokufunda i-eevblog nokuyizama.Yenza izixhumi ze-molex kk nakho konke. izinhlobo zezinto, vele uthenge isikhunta esilungile insert.pressmaster ithengiswa ngaphansi kwamagama amaningi, ngakho ithole ngesithombe bese ubona ukuthi imaphi amanye amagama ekubhalele yona.
Yilapho eqanjwe khona kabusha.wiha ayihlanganise lutho nalokhu, kodwa uphawu olukhulu!Okungcono kakhulu ukugwema lokhu;thola noma yiliphi igama ongalithola ku-MCT ukukongela imali.Izibunjwa ziyafana, azikho uphawu kuzo, cindezela nje umphathi (ngokubona kwami; nginesikhunta esingaba ngu-3 noma esi-4 kuzo zonke izidingo zami).
https://www.amazon.com/gp/product/B00H950AK4/ iyona engiyisebenzisa ekhaya. Ishibhe kakhulu, kodwa ibonakala ifana nalena ethengiswa i-ferrulesdirect.com (umthengisi esiwusebenzisa lapho ngisebenza khona).
Ngaso sonke isikhathi sebenzisa amathuluzi, ikakhulukazi ama-crimpers, ngokucophelela.Into ebukeka ifana esithombeni esine-res ephansi ekhompyutheni yakho ingase isho ukuthi isikhunta sibi kakhulu phakathi kwenguqulo ye-Amazon kanye nenguqulo ethengiswa umphakeli ohlonishwayo.Izifa zibaluleke kakhulu ingxenye: uma zingaklanywanga futhi zenziwe ngokucophelela, awukwazi ukuthembela ku-100% kwikhwalithi ye-crimp yakho, ehlula yonke inhloso yokusebenzisa ama-ferrules.
I-Unior 514 kanye ne-gedore 8133 zinhle kakhulu ekugwebeni okusheshayo uma ungafuni ukuphatha amathuluzi amaningi esikhwameni sakho.Eshabhu, kuhle ukuba namathuluzi akhethekile.Emsebenzini sine-gedore ne-knipex ezisebenze kahle iminyaka engu-7 edlule.
Kuthiwani ngokubopha iziphetho zezintambo? Lokhu kuqhathaniswa kanjani nama-ferrules?Kuphinde kususe i-oxidation futhi kuqede izikhala zomoya ezizungeze izintambo.
Bengihlala ngicabanga ukuthi lokhu kuwumbono omubi, njengoba i-solder empeleni iwukumelana okuphezulu kakhulu.
Iyasebenza, kodwa ngaphandle kwempikiswano ebaluleke kakhulu yokukhululeka komshini.Ngibone iziphetho zezintambo ezithayiwe eziningi kakhulu eziphuka kalula ekushintsheni phakathi kwezingxenye ezithathiwe nezingafakwanga.
Ukwenza izinto zibe zimbi nakakhulu, ukuphela kwe-solder kunikeza iphuzu lokucindezeleka okwenza kube lula ukuphuka
Ukwenza izinto zibe zimbi nakakhulu, i-solder iyathandeka futhi inelastic, ngakho-ke noma isikulufu siqinisiwe, noma yikuphi ukuguqulwa komshini kuzobangela ukuthi uxhumano lube lukhulu kakhulu.
Ukwenza izinto zibe zimbi nakakhulu, ukuphela kwe-solder kunikeza iphuzu lokucindezeleka okwenza kube lula ukuphuka
Uma ngikhumbula kahle, kwenza ingxenye yocingo ekugcineni kwe-solder ibe lula kakhulu ukuphuka.Ngakho-ke uzoba nethiphu elihle eliqinile, kodwa ucingo luzophuka ngokushesha.
yebo.I-Solder ingakwazi ukufaka intambo kwi-insulation futhi ibe yindawo ebuthakathaka yokukhathala.
Ezinyangeni ezimbalwa ezedlule, ibhayibheli le-NASA lakwenza kwacaca ukuthi ungavumeli i-solder ikhuphuke ngo-1-2mm phambi kwe-insulation yocingo.Lapho ucingo ludinga ukuxhunywa emshinini wokugunda, okwenzayo ukusebenzisa i-Litze wire ishibhile, hhayi uhlobo lomucu ovalekile) ngoba ulimele ngokukhululekile kumakhulu emicu. Bese uba nocingo oluguquguqukayo ngokwanele ukuba lunganqamuki.
Intambo ye-Litz, njengoba negama libonisa, iyinqwaba yezintambo ezingazodwana ezivalekile.Ayikho "inguqulo eshibhile" yezintambo ezingagqunyiwe, njengoba lokho kwehlula injongo yentambo ye-litz. Udinga nje ukubala kwentambo ephezulu noma intambo "eguquguquka kakhulu". , ayenzi okuningi ezindaweni ezibuthakathaka ezidalwe ukushisela.
Leso akusona isizathu sokuthi kungani ungadayisi izintambo kumatheminali ngezikulufu.Uma kunjalo, kulungile inqobo nje uma izintambo zingagobi noma zidlidlizele eduze kwamatheminali.Inkinga ukuthi i-solder ijwayele ukukhasa (“ukugeleza okubandayo ”).Iyawohloka ngokuhamba kwesikhathi, ilunga lilahlekelwa ukucindezelwa, bese uba nokuxhumana okuxekethile nakho konke okudingayo.
ayilungile.Idala iphuzu elibuthakathaka ngokushesha ngemva kokuhlanganisa i-solder, futhi ukugoba ngokweqile ikhebula kungalimaza ikhebula kulelo phuzu eliqondile.Imikhono (ama-ferrules) aneziphetho zepulasitiki kulula kukhebula ngisho noma udonsa kanzima ikhebula.
Uthayela awuqinile ngempela, kodwa uzokonakala ngokuhamba kwesikhathi.Ngenxa yalokho, ukuxhumana obekuqiniswe ngesikhathi sokufakwa kungaxega ngokuhamba kwesikhathi.uxhumano oluxegayo -> ukumelana okuphezulu -> izinga lokushisa eliphakeme -> ithani eliqinile elingaphansi -> ukuxhumana okuxekethile...uyazi kwenzakalani
Futhi, ithini lingangena ku-insulation bese lenza indawo eqinile endaweni ethile kude netheminali - uma unebhadi, yilapho izintambo zocingo ziqala khona ukugqashuka, kubangele amaphutha angabonakali.
Inkinga enkulu, ngaphezu kweqiniso lokuthi izingxube ze-tin noma ze-tin+lead zithambile kakhulu, "ukugeleza okubandayo" kukathayela kuphuma kusikulufu ngokusebenzisa amabhayisikili ashisayo kanye nengcindezi, ngokushesha noma kamuva kudala ukumelana okukhulu nokuxhumana.
Isizathu sesithathu engizwile ngokumelene ne-solder ukuthi i-solder ithambile kakhulu futhi ngokuhamba kwesikhathi ukuxhumeka kwesikulufa kuzokhululeka.
Ukugeleza okubandayo ngaphansi kwengcindezi kuyisizathu esifanayo sokuthi izintambo zamandla ze-aluminium ezindala ziyingozi kakhulu.Ngokuhamba kwesikhathi, ukuxhuma kuyaxega, ukumelana kuyakhuphuka + ukuxhumeka okumpofu kungabangela ukugoqa.
Angithandi ukuyithola esizeni.I-Solder iqinile futhi ibushelelezi, ngakho-ke i-terminal block ayiminyanisi futhi ibambelele kuyo njengethusi elinemicu ethambile.Ama-Ferrule crimpers afaka ama-serrations ku-crimp, ukuze ibambe kangcono kune-solder.
Intambo ethayiwe yamatheminali e-screw ingumbono omubi ngoba ngisho nasezingeni lokushisa lekamelo i-solder izoshintsha kancane ngaphansi kwengcindezi futhi njengoba izinga lokushisa lijikeleza, lizogeleza liphume ejoyintini lehlise indawo yokuxhumana futhi likhulise ukumelana, ngaleyo ndlela lishise, kuholele ekutheni umphumela omuhle wempendulo.
I-tin plating ithambile kunethusi elingenalutho.Ngenxa yalokho, izikulufi zingalahleka ngokuhamba kwesikhathi ngokushesha kunama-ferrules noma ama-lugs.
Ngiyazi ukuthi e-Europe, izintambo eziboshiwe ngokuvamile zifakwa ithini ngaphambi kokuthi izisetshenziswa eziningi zihluleke noma zishise, futhi ukugoqa manje sekuyinkinga.
Idala inkinga ngokukhululeka kwengcindezi…imvamisa iphuka ngokuphelele lapho i-solder iphelela khona, njengoba ivumela ukugoba okubukhali kakhulu (izintambo ezidayisiwe ziqinile, izintambo ezingadayisi azikho….
Angisoze ngaphakamisa intambo yokunamathisela.Ikakhulukazi uma kunokudlidliza noma ukunyakaza, ikhebula lakho lingaphuka ngesikhathi esifushane.
